DRAW-BAR EQUIPMENT.

Application filed August 13,1909.

Specification of Letters Patent.

Patent ed May 6, 1913.

Serial No. 512,634.

y, State of Ohio. have invented a certain new and useful Improvement inDraw-Bar Equipments, of which the following is a specification.

The object of this invention is to provide a an improved draw barrigging or equipment in which the construction is simplified, cheapenedand rendered more durable and in which the draw bar can be removed forrepairs or replacement with great facility.

The invention is embodied in the details of construction hereinafterdescribed and pointed out in the appended claims.

In the accompanying drawings forming a part of this disclosure, Figure 1is a central vertical section taken longitudinally of the car but withthe draw bar shown in full lines; Fig. 2 is chiefly a side elevation ofone side of the equipment with the draw har removed; Fig. 3 is a crosssection on the line www Fig. 1; Fig. 4 is a top plan view of the cheekplate removed from the sill; Figs. G and 7 are side, end and plan views,respectively, of the timber key. Fig. 8 is a side view of a fraction ofthe outer end of the reinforcing plate showing how it is notched toreceive the timber key.

In the views 8, 8, designates the usual longitudinal sills which, asusual, extend the y entire length of the car at the under side if thefioor 9. The characters 10', 10, desig- .iate the draft timbers whichare secured to the sills 8, 8. by means of bolts 11, but I firstsecurein the sills timber keys like that lshown in Figs. 5, 6 and 7. Thesekeys are metallic devices of clip form comprising a central base or lugportion 1Q, with parallel cars 18 rising therefrom at each end. and ahollow dowel 14, with external ribs or feathers 14, rising from themiddle of the lug portion 12. The sills are tirst bored with holes toreceive the dowel body and to permit the passage of the bolts 11, andthe key is driven into place in the sill, the feathers penetrating thewood of the sill and affording an extended surface for strains. Afterthe keys are driven home they are further secured by horizontal bolts l5passed through suitable holes in the ears 1S. 0n the inner side of thesills and between the sills and the ears are preferably secured metallicreinforcing plates 16 which are notched as at 16"l to receive the keysand are secured by the bolts 15. The outer ends of the plates 16 aresecured by angle pieces 30 to the end sill 31.

The cheek plates, of which there are two and which are symmetricalduplicates of each other and secured to the draft timbers by bolts 17.These cheek plates each have thickened portions 18, 18, provided attheir upper ends with notches 19, 19, to fit or engage on the lugs 1Q ofthe timber key. The cheek plate also has a central rib 20 which inconjunction with the portions 18, 18, forms cavities Q1, Q1, open attheir lower ends. The lower ends of the thickened portions 18, 18, andthe central rib 20 of each cheek plate, have recesses formed in them,all alining horizontally with each other, and through which a key 22 canbe passed endwise and removably secured by means of a cotter pin 23 orother suitable device. The key 22 closes the lower ends of the recessesQ1 after the draw bar is put in place. designates the draw bar stem.This draw bar stem has secured upon it a yoke 25. and placed within theyoke are suitable springs 2G and followerl plates 27 of which there arefour, one at each end of each spring as shown. The ends of the followerplates project beyond the opposite edges of the yoke Q5 and tit in thecavities 21, 21.

As before indicated the draw bar with its springs and follower platesare put into place by pushing it up into the equipment with the ends ofthe follower plates passed into the recesses Q1 after which the keys 22are inserted and secured as described. The keys QQ thus subserve thefunction of securing the draw bar in place and the draw bar can beremoved by removing t-he said keys. The strains on the draw bar stem arethus borne immediately by the cheek plates and draft timbers which inturn transmit them to the sills and the bolts connecting the drafttimbers to the sills, and because these bolts press against the metallicportions of the timber keys a very rigid and secure connection of thedraft timbers with the sills is obtained.

IVhat I claim is:

1. In a draw bar equipment, the combination with the longitudinal carsills and draft timbers, of a key between the timbers and sillsconsisting of a metallic member of clip form to straddle the sill andhaving its central portion provided with a hollow dowel to enter thesill and for the reception of a bolt.

2. In a draw bar equipment the combination with the longitudinal earsills and draft timber, ot a key between the timber and the sillsConsisting of a metallic member of clip form to straddle the sill andhaving its central portion provided with a hollow dou'el to enter thcsill and for the reception ot a bolt said dowel provided with externalribs or feathers.

S. ln a draw bar equipment, the Combie nation with the longitudinal carsills and draft timbers, a notched reinforcing plate on the sills, acheek piece on the draft timbers and a timber key between the sills anddraft timbers said timber key engaging the notched portion of thereinforcing plate and the cheek piece engaging the timber key.

4. In a draw bar equipment, the combination with the longitudinal carsills and draft timbers and a metallic cheek piece, of a key between thetimbers and sills Consisting of a metallic member oi clip form includingears having bolt holes`r said metalliey mem her to stradille the sillsand having its central portion provided with a hollow dowel to enter thesill and tor the reception of a bolt.
